You may have heard of backflow testing but have yet to understand what it is or why it’s essential. Backflow testing is the process of ensuring that water flows in the correct direction in your plumbing system. It is important because if water starts flowing backwards, it can contaminate your drinking water supply with harmful bacteria and chemicals.
This blog post will explain backflow testing and why it’s so important. But first, let’s better understand the meaning of backflow.
What is Backflow?
Backflow is a plumbing phenomenon in which wastewater from your home flows backwards and into your freshwater supply. Doesn’t that sound unpleasant? Yes, it is, and it is also a health risk. Because of the chemicals, the mixture of fresh water and waste can destroy the plumbing from within and cause terrible health problems. Backflow occurs when water mains bursts, excessive demand during firefighting operations, or other times of high need.
Backflow may happen if a water pump is cross-connected to the internal water plumbing system and pumps bore water at a pressure higher than the water mains pressure (back pressure).
Suppose a property’s drinking water supply is connected to a source of pollution via a cross-connection or simply a hose submerged in a container of liquid. In that case, pollutants enter the water supply when a sudden drop in water mains pressure.
You can fix this by installing a backflow preventer but eventually, to ensure that it doesn’t hinder your daily routine, you must think about hiring a professional plumber with expertise in hot water repairs in Melbourne.
Reasons to Choose Backflow Testing
1. There are numerous potential contaminants
Do you have inground pools, lawn irrigation systems, dishwashers, boiler heaters, or even washing machines? If this is the case, contaminants are almost certainly present. While we cannot guarantee that these contaminants will always find their way into clean water, the possibility exists.
Contaminated water can be a breeding ground for bacteria that cause diarrhoea, cholera, dysentery, typhoid, and hepatitis A. It is best to perform backflow testing to ensure you receive a clean water supply. That way, you can discard the chances of contaminated water entering your freshwater supply.
2. Mandated by law
Backflow testing is mandated not only by the Environmental Protection Agency (EPA) but also by local municipalities. Furthermore, only 24/7 plumbers in Melbourne certified to conduct the testing are permitted.
Backflow testing consists of several steps, including pressuring the water system, inspecting each component to ensure proper operation, and replacing any valves that need to get replaced. As a result, it can only be done by a professional.
3. It reduces liability
If you have any water-using equipment installed, your home may be vulnerable to backflow. Installing a backflow preventer and performing backflow testing can help to reduce this potential liability.
Not only will you and your family remain healthy, but your expensive equipment and plumbing will get protected from damage or severe malfunction, which can be costly to repair.
4. It can detect plumbing issues
Plumbing issues do not occur at random. Most of us miss them because we are unaware of how these problems appear. Fortunately, hiring professionals for backflow testing can detect a number of them.
5. You’ll have reassurance
We understand that the prospect of your freshwater supply becoming contaminated is frightening. That is how everyone feels. However, installing a backflow preventer can reduce the likelihood of this occurring. Also, remember that’s not all; you should also perform backflow testing to ensure everything is working correctly.
During testing, the plumbers also ensure that any backflow issues get addressed so that you don’t have to deal with contamination. It means you can relax about the quality of your drinking water.
Types of Backflow Preventers
1. Device for Lowering Pressure Zones
The RPZ preventer is ideal for protecting against high-risk water contamination. Such backflows can be extremely dangerous to people. Every year, technicians must inspect the valve to ensure it is in good working order.
The reduced pressure zone device has two check valves and a pressure monitoring chamber. An additional drain on the preventer relieves any excess stress. As a result, the tension in the monitor chamber barely exceeds the pressure in the water supply.
2. A Gap in the Air
One of the most common and effective backflow preventers is the air gap. This system separates the container from the water source. Plumbers typically install air gaps in residential sinks and bathrooms.
When you notice a water leak in your bathroom, call your plumber to solve two problems at once. Installing an air gap preventer in your bathroom will be just as effective.
3. Breaker of Atmospheric Vacuum
The atmospheric vacuum breaker is a preventer with an elbow shape and an internal valve that prevents water backflow. This system’s functionality is dependent on pressure. As a result, it is feasible to install it downstream, preferably on pipes.
4. Loop Hydrostatic
A hydrostatic loop forms when pipes get arranged vertically. For optimal performance in this configuration, the loops must be at least 33 feet tall. In a water system, this design prevents backflow and syphoning.
5. Check Valves on Both Sides
Dual check valves are commonly used in residential homes to prevent backflow caused by cross-connections. These dual check valves have a limited application, and homeowners should be cautious of the resulting thermal expansion. If you have this device in your home, your water supplier can advise you on how to use it.
6. Flood Gate Valve on Autopilot
The floodgate valve prevents wastewater from entering the central water system. These tools rely on air pressure to function automatically. They control backwater flow as long as they are locked.
